Abstract
A logic circuit has two pairs of input terminals to each of which is applied a pair of input signals opposite in phase and a pair of output terminals for deriving a pair of output signals corresponding to the logical states of the two pairs of input signals. The logic circuit is further provided with a holding circuit which is adapted to hold the output signals in the same logical state when a pair of input signal having the same phase are applied to the input terminals.
